Abstract
The chemical constituents of essential oil were obtained from the fresh leaves and flowers of Hyssopus officinalis L. (Lamiaceae) by hydro distillation method analyzed by gas chromatography and gas chromatography mass spectrometry. Hydro distillation method was used to extract the essential oil. Thirty-five compounds were identified, accounting for 92.13% of the total oil with 0.75% (v/w) oil yield in the essential oil of the leaves. The main constituents of the essential oil were Iso pinocamphone (38.47%), Pinocomphone (13.32%), n-decane (8.67%) and Pinocarvone (5.34%). Thirty-six compounds were identified, accounting for 98.68% of the total oil with 1.38% (v/w) oil yield in the essential oil of the flowers. The main constituents of the essential oil were Iso pinocamphone (40.25%), Pinocomphone (14.92%), n-decane (8.63%) and Pinocarvone (6.76%). Key words: Hyssopus officinalis L., iso pinocamphone, volatile oil, gas chromatography mass spectrometry (GC/MS).
Highlights
Hyssop (Hyssopus officinalis, synonym Hyssopus decumbens) is a herbaceous plant of the genus Hyssopus native to Southern Europe, the Middle East, and the region surrounding the Caspian Sea
The study of the analysis of H. officinalis L. essential oil under investigation showed that thirty-five compounds, accounting for 92.13% of the total oil with 0.75% (v/w) oil yield were identified in the essential oil of the leaves
The quality and quantity of the materials forming H. officinalis L. essential oil had some differences and similarities with the cases reported in other regions
Summary
Hyssop (Hyssopus officinalis, synonym Hyssopus decumbens) is a herbaceous plant of the genus Hyssopus native to Southern Europe, the Middle East, and the region surrounding the Caspian Sea. The essential oil of H. officinalis plant has been studied in Iran and other countries but the chemical composition of the essential oil of H. officinalis has not been determined in Khalkhal, Iran. In the present work we have analyzed the chemical composition of the leaves and the flowers of H. officinalis L. that grow in Khalkhal and the results were compared with various origins in other countries.
